Here is a partial sequence showing a corallimorph after it has been fed some pieces of fish food.

5:52:48pm: Polyp is begining to open after injesting food. Engorged mouth is just visible.

5:52:54pm: Polyp is open a little futher.

5:53:10pm: Polyp opens further.  The mouth is still engorged but is starting to shrink.

5:53:20pm: As polyp opens the mouth shrinks further.

5:54:40pm: Polyps is back to normal open state and mouth is almost back to normal.
